Nice, although IMO they've got it wrong: They should keep the coins and lease the units at a lower price than traditional systems of a comparable wattage.
And I can't also get bullshit "feature" updates, and my device can't be remotely bricked, and it doesn't need the mothership servers to be up - so again, my device won't die when the company gets acquihired, stops pretending to provide value and pivots to writing blogposts about their incredible journey.
